By providing the reinforcing component 4, the load-bearing strength between the two support plates 2 can be strengthened, thereby improving the overall strength of the support 1 and the support plate 2.

[0028] The reinforcing component 4 includes hollow rods 41, with several hollow rods 41 arranged. Movable rods 42 are slidably mounted at both ends of each hollow rod 41. By arranging multiple hollow rods 41 and movable rods 42 between two hollow rods 41, the two support plates 2 can be formed as a whole, reinforcing the area between the two support plates 2 and preventing rocks from falling from the top of the mine roadway. A groove 43 is provided on the lower surface of the hollow rod 41, and a locking block 44 is fixedly mounted at the other end of the movable rod 42. The locking block 44 is slidably mounted at one end of the groove 43. With the groove 43 and the locking block 44, the locking block 44 can slide horizontally along the inner wall of the groove 43, ensuring stable horizontal sliding of the movable rod 42 within the hollow rod 41. The hollow rods 41 and movable rods 42 are located between the two support plates 2. Both sides of the support plate 2 are provided with arc-shaped grooves 45. One end of the movable rod 42 is in contact with the inner wall of the arc-shaped groove 45. By providing the arc-shaped grooves 45, when installing the hollow rod 41 and the movable rod 42, the end of the movable rod 42 is inserted into the arc-shaped groove 45, so that the hollow rod 41 and the movable rod 42 can be installed between the two support plates 2. The lower surface of the two support plates 2 is provided with several threaded holes 46. The threaded holes 46 are connected to the arc-shaped grooves 45. One end of the movable rod 42 is threadedly rotatably installed with a locking screw 47. The locking screw 47 is threadedly rotatably connected to the inner wall of the threaded hole 46. One end of the locking screw 47 is fixedly provided with a No. 1 hexagonal seat 48. By rotating the No. 1 hexagonal seat 48, the locking screw 47 can pass through the threaded hole 46, so that the movable rod 42 can be fixed on the support plate 2.

[0029] A protective component 5 is installed between the two support plates 2. This component protects the area between the two support plates 2, preventing falling debris from the top of the mine roadway. The protective component 5 includes a wire mesh 51, which is detachably installed between the two support plates 2. A fixing plate 52 is fixedly installed at one end of the movable rod 42, and an upper pressure plate 53 is fixedly installed at one end of the fixing plate 52. A slot 56 is provided on the upper surface of one end of the movable rod 42, and a lower pressure plate 57 is slidably installed within the slot 56. The edge of the wire mesh 51 is located between the upper pressure plate 53 and the lower pressure plate 57. A [missing information - likely a type of material] is fixedly installed on the lower surface of the upper pressure plate 53. Anti-slip pad 55 has its lower surface in contact with the upper surface of the edge of the wire mesh 51. Anti-slip pad 58 is fixedly installed on the upper surface of the lower pressure plate 57. The upper surface of anti-slip pad 58 is in contact with the lower surface of the edge of the wire mesh 51. By setting up the upper pressure plate 53, anti-slip pad 55, lower pressure plate 57 and anti-slip pad 58, as the lower pressure plate 57 and anti-slip pad 58 rise toward the side of the upper pressure plate 53, the edge of the wire mesh 51 can be pressed between the upper pressure plate 53 and the lower pressure plate 57. Anti-slip pad 55 and anti-slip pad 58 can improve the stability of the pressed wire mesh 51.

[0030] Two guide grooves 59 are provided on the side wall of the slot 56. A guide block 6 is slidably provided on the inner wall of the guide groove 59. A connecting frame 61 is fixedly provided on one side of the guide block 6. One end of the connecting frame 61 is fixedly connected to the lower surface of the lower pressure plate 57. By setting the guide groove 59, the guide block 6 and the connecting frame 61, the guide block 6 can slide vertically along the inner wall of the guide groove 59, so that the lower pressure plate 57 can be vertically guided by the connecting frame 61, so that the lower pressure plate 57 can be kept vertically raised and lowered. A threaded rod 62 is threadedly installed on one end of the movable rod 42. One end of the threaded rod 62 extends into the slot 56 and is rotatably connected to the lower surface of the lower pressure plate 57. A second hexagonal seat 63 is fixedly provided on the other end of the threaded rod 62. By setting the threaded rod 62 and the second hexagonal seat 63, when the second hexagonal seat 63 is rotated, the threaded rod 62 can be rotated, and the threaded rod 62 can drive the lower pressure plate 57 to rise and fall vertically.

[0031] Working principle: Before the support plate 2 is installed on the top of the bracket 1, the operator first selects a certain number of hollow rods 41 and movable rods 42, so that the ends of multiple movable rods 42 enter the arc-shaped grooves 45 of the two support plates 2 respectively, and then manually rotates multiple No. 1 hexagonal seats 48 so that multiple locking screws 47 thread through the corresponding threaded holes 46 and rotate at the ends of the movable rods 42.

[0032] Then, cut the wire mesh 51 to the appropriate length and width so that the edges of both ends of the wire mesh 51 pass between multiple upper pressure plates 53 and lower pressure plates 57. After the wire mesh 51 is laid, the operator manually rotates multiple No. 2 hexagonal seats 63 to rotate multiple threaded rods 62. The threaded rods 62 drive the lower pressure plate 57 to rise vertically. With the help of the upper pressure plate 53, the edges of both ends of the wire mesh 51 are pressed tightly, so that the laid wire mesh 51 is fixed between the two support plates 2.

[0033] Then, manually pull the movable rods 42 at both ends of a hollow rod 41 to adjust the overall length between the hollow rod 41, the two movable rods 42, and the two support plates 2 to meet the overall length of the bracket 1. Then, place the two support plates 2 on the top of the four brackets 1 and fix them with bolts.
